What To Expect
Besides making sure you never have to touch QuickBooks again, I also
✓ Proactively flag financial concerns before they become problems
✓ Reduce the overwhelm of running a clinic
✓ Make it easier for you to handle subcontractors correctly
✓ Help you figure out HST, exempt and everything in between
✓ Guide you through the admin side when you decide to incorporate
✓ Answer of your questions (business-related or not 😉)
My goal is to give you the space to breathe, dream big, and focus on the work you were truly meant to do.

Hi, I'm Katrien...
I'm a passionate bookkeeper, business analyst, wife and mom.
I started Second Banana in 2023, combining my background in engineering and finance with a strong passion for structure, financial analysis and supporting people behind the scenes.
Today, I help clinic owners and solo health practitioners who are amazing at what they do but are feeling a pressure to hold it all together while being overwhelmed by the business side.



What My Happy Clients Say
Katrien's skilled competence has lifted weight off my shoulders and freed up parts of my mind to focus on other aspects of our business.
Beth, co-owner of a mental health private practice
One of her greatest strengths is her unwavering reliability. I always knew my books would be handled with the utmost professionalism and attention to detail.
Kathy, owner of a home care service provider
